I've honestly never seen this one before:
Warning: session_start(): The session id contains invalid characters, valid characters are only a-z, A-Z and 0-9 in /www/html/image_catalog/index.php on line 30
Here is the session id pulled from $PHPSESSID:
PHPSESSID=f2d869aae5159c73acb617c15cd6d562
Anyone ever run into this one, this is a new one!
